Salicacese. 
Catkins on leafy stalks, more lax than in the last Cap¬ 
sules glabr. (v. leiocarpa = S. stylaris Ser.), or tomen- 
tose (y. eriocarpa = S. nigricans Ser.), long-pedicelled, the 
pedicels 3—4 times as long as the gland. A very variable 
species.—Water-side, thickets, up to 2000 m; distrib. 4 
nigricans Sm. 2014. 
24 (21). Young twigs and buds pubescent-tomentose. Ls ob- 
ovate-oblong, gen. broader towards the top, dead green, 
dull and pubescent above, gray-tomentose underneath. 
A medium sized shrub with thick branches.—Water¬ 
side, thickets; distrib. 3 ... cinerea L. 2015. 
— Young twigs and buds glabr. or faintly pubescent 25 
25. Ls 2—4 cm long, pubescent and| dead green above, to- 
mentose and wrinkled underneath, obovate or obovate- 
oblong, cuneiform at the base. Gen. a low shrub, very 
branchy, with slender, divaricating branches. Catkins 
and ls smaller than in S. cinerea and Caprea; scales 
rust-coloured at the top.—Peat-mosses, damp forests; 
distrib. 3 . . . . . . aurita L. 2016. 
— Ls about 5—15 cm long, when full-grown glabr. or al¬ 
most glabr. above . . ■ . . . . 26 
26. Catkins almost sessile, preceding the ls. Ls broad- 
oval or elliptic-orbicular, broadest at the middle, short- 
acuminate, more or less white- or gray-tomentose under¬ 
neath. A tree or shrub attaining a height of 9 m .— 
Water-side, thickets; up to the Alp.; distrib. 3 
Caprea L. 2017. 
— Catkins gen. appearing with the ls, on leafy stalks, 
looser than in the last. Ls obovate-oblong or oblong- 
lanceolate, with cuneiform base, broadest towards the 
top, acuminate, when full-grown pubescent or almost 
glabr. underneath ....... 27 
27. Ls large, 6 — 15 cm long, gen. obovate-oblong or obovate- 
lanceolate, bluish and pubescent, when full-grown almost 
glabr. underneath, rather firm, the nerves forming a 
denser net-work than in the last. Pedicels 4—5 times 
as long as the gland. A form with ls grayish-tomentose 
on both sides (v. cinerascens) should not be confused 
with the following species.—Mount., subalp. and Alp.; 
Jura up to Lagern, fairly distrib. 5 grandifolia Ser. 2018. 
■— Ls gen. smaller than in the last, covered when young, 
as also the capsules, with a woolly, white tomentum, 
when full-grown thin, easily turning black in drying. 
Lateral nerves less numerous (9—14) than in the last, 
more distant, consequently the net-work looser. Catkins 
longer-stalked, very lax. The filaments of the stas more 
hairy. S. pubescens Schl., S. grandifolia albicans Ser., 
S. grandifolia lanata Gaud., S. Laggeri (glauca-grandi-
